Forum posters describe early October daytime temperatures as commonly in the low 70sF, mild enough for some pool time by day but cooling off noticeably once the sun goes down. Posters consistently flag the coastal 'garua' fog as a real feature of this stretch of the Peruvian coast from roughly May through October, often keeping mornings overcast even when the afternoon clears, and are direct that the sea itself stays cold year-round thanks to the Humboldt Current regardless of how warm the air feels. Posters generally recommend packing fleece layers and a light raincoat rather than a winter coat, describing October as genuinely spring-like on land - comfortable for sightseeing and the Ballestas Islands boat trips - while the ocean itself remains a cold-water experience.

Most of Peru's December forum chatter is really about the Andean highlands around Cusco and Machu Picchu, where the wet season is just getting going - that's a different climate story entirely from Ica's coastal desert. Ica itself stays close to its year-round dry, sunny pattern regardless of what the Andes are doing at the same time, with real rain a genuine rarity here even in December. It's worth remembering these are two separate weather systems within the same country when planning a Peru itinerary that includes both.

Forum posters describe June as winter in this coastal desert region, with comfortable daytime temperatures around Ica and nearby Paracas but genuinely strong afternoon winds worth planning around. Posters are careful to distinguish this coastal desert climate from Peru's much colder Andean highlands (Cusco, Puno and similar high-elevation stops on a broader itinerary), where nighttime temperatures can drop toward freezing and heavy layering is standard advice - conditions in Ica and at the Huacachina oasis specifically stay milder than that highland cold even in June. Posters note June's relative quiet is a real plus at Huacachina, with the sand dunes seeing lighter crowds than peak season.
